RDMA/hns: Fix inappropriate err code for unsupported operations

[ Upstream commit f45b83ad39f8033e717b1eee57e81811113d5a84 ]

EOPNOTSUPP is more situable than EINVAL for allocating XRCD while XRC
is not supported and unsupported resizing SRQ.

Fixes: 32548870d438 ("RDMA/hns: Add support for XRC on HIP09")
Fixes: 221109e64316 ("RDMA/hns: Add interception for resizing SRQs")
